FLEXIBLE: COUPLING.

SPECIFICATION forming part of Letters Patent No. 700,246, dated May 20,1902. Application filed September 14, 19 00- Serial Ila 30,062. (Nomodel.)

To all.wh0m it may concern:

Be it known that we, CHARLES L. SCHULTZ and ROBERT A. SCHULTZ, citizensof the United States, residing at Chicago, county of Cook, and State ofIllinois, have invented a new and useful Improvement in FlexibleCouplings for Shafts, of whichthe following is a specification.

Our invention relates to that class of coupling by rneans of whichtheshaft may as oocasion requires depart from a straight line, alsoexpand and contract longitudinally to a limited extent to accommodateitself in a shiftin g or movable bearing, rendered necessaryoccasionally, as in traction-vehicles, where the rotary shaftoperatively connected with the reversing-gear has one of its bearingssuspended from the body, which rests on springs which are elevated anddepressed according to the load carried. The shaft must then accommodateitself in length to the shifting movement of the body. We accomplishthis purpose by means of the device illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of the flexiblecoupling. Fig. 2 is an endview-of the-same. Fig. 3. is a face view withone of the disks removed. Figs. 4 and 5 are details of the swivelmembers. 1

Similarletters refer to similar parts throughout the several views.

In the construction of the device, a a represent the divided shaft. band b are two facing disks on the ends of thedivided shaft a. Eachfacing disk is provided with two projecting lugs c andc at oppositepoints and said disks are connected-,by-m'eans of two'swivels'constructed as shown in Figs. 4 and 5, each comprising two members atand e, having bent arms 2' and. *5, the arm e having a socket m and thearm a" having a collar n, which is adapted to fit into the socket m andpartially turn or play in the socket. t" are attached tothe lugs c and con the face of the disks-that is to say, the end of one arm to a lug onone of the disks, the other arm to a lug on the opposite disk; so thatthey appear diagonally across the face of the disks, as shown in theillustration, Fig. 1. This construction permits the disks to approacheach other or to separate or increase the distance between the disks toshorten or lengthen the shaft, and also to permit the shaft to deviateto a limited extent from a straight line without afiecting the power ofthe shaft.

Having thus described our invention, what we claim as new, and desire toprotect by Letters' Patent, is-

The arms '5 and ha flexible coupling, a divided shaft, a

disk on each of the ends of said divided shaft,

said disks facing each other, two lugs pro jecting at a right angle fromthe face of each disk, said facing disks connected by means of twoswivels having an extension-arm on each end, and each arm bent at anangle of forty-five degrees and engaging a lug on said facing disks,substantially as specified.

Intestimony whereof we affix our signatures in presenceof two witnesses.
